Seattle Mariners Executive Vice President & General Manager of Baseball Operations Bill Bavasi announced today that the Mariners have named Rafael Chaves the Major League pitching coach and Jeff Pentland the Major League hitting coach for 2006. In addition, Dan Rohn has been named administrative coach for the club.

"We believe Rafael and Jeff were the best guys available for our needs," Bavasi said. "Both have shown the ability to get the most out of the guys they coach. They are good communicators, hard workers and talented baseball coaches."

Chaves, 37, has spent eight seasons as a coach in the Mariners organization, the past two as the pitching coach at AAA Tacoma.

"Anytime we can promote from within we try to do that as recognition that our minor league coaches are very good at what they do, but that's not the main reason we hired Rafael," Mariners Manager Mike Hargrove said. "The part that impressed me was his intelligence. He understands pitching and he knows how to teach pitching and he's got great communication skills. I like his intensity; I like his intelligence; I like his baseball knowledge...when I interviewed him there were just a lot of things I really liked.

"Raffy has the respect of pitchers on our staff and pitchers coming up. He was absolutely the perfect fit for us at this time."

Chaves began his coaching career in 1998 at rookie Peoria. He advanced to short-A Everett in 1999 and to class-A Wisconsin in 2000. He was pitching coach in 2001 at high-A San Bernardino and spent the 2002-2003 seasons at double-A San Antonio. Chaves helped his teams advance to the post season five times in eight seasons as a minor league coach. Tacoma led the PCL in shutouts in 2005 and San Antonio led the Texas League in ERA in 2003, and was second in ERA and first in strikeouts and shutouts in 2002. San Bernardino tossed a club-record 12 shutouts in 2001 and Wisconsin led all Mariners affiliates in ERA in 2000.

"I am honored that the Mariners have given me this great opportunity," Chaves said. "It really shows the trust they have in me. It's important for the Mariners organization because it shows that we believe in our people, me being a guy who started in rookie ball. I know it means a lot to me and the other people who have been with this organization for a long time because it demonstrates the trust we have with people at all levels of the organization."

Chaves spent 12 seasons as a minor league pitcher in the San Diego (1986-92), Baltimore (1993), Florida (1994) and Pittsburgh (1995-97) organizations.

Pentland, 59, has spent nine seasons as a big league hitting coach, including the past three seasons (2003-2005) as the Kansas City Royals hitting coach.

"We worked extremely hard to identify the best people who have had success with a diverse group of hitters, and Jeff stood out of this group," Hargrove said. "He's a creative guy and has, without question, a great work ethic. If he was a basketball player, you'd call him a gym rat, and in his role, he's a cage rat. That's what a hitting coach needs to be to be successful and Jeff has had success. I'm extremely excited that we got Jeff as our hitting instructor. It will be good for our hitters and our baseball team."

Pentland was the Chicago Cubs' hitting coach for six seasons (1997-2002), joining the Cubs on July 14, 1997, after starting the season as the New York Mets minor league hitting coordinator. He began his big league coaching career as the Florida Marlins' hitting coach in July, 1996.

"Seattle is a great organization," Pentland said, "full of really talented baseball people, which was very important to me. The Mariners have had great success over the years and it's clear they want to get back to winning as quickly as possible. The players are there. It's a matter of getting them going in the right direction, and hopefully I can help make that difference."

Jeff was in the Marlins organization from 1992-96, spending 1995 and the first half of the 1996 season as the hitting coach at AA Portland, ME, in the Eastern League. He spent the 1993-94 seasons as the hitting coach at Elmira in the New York-Penn League and was a scout for the Marlins in 1992-93.

He began his coaching career as an assistant at Mesa (Ariz.) Community College in 1971 and was the Junior Varsity Coach at Arizona State in 1973. He spent nine seasons as an assistant coach at University of California-Riverside, where the Highlanders won a pair of national titles during his tenure.

Pentland played college baseball at Arizona State, where he was a member of the Sun Devils 1967 national championship team. He was inducted into the ASU Hall of Fame in 2002. Jeff played minor league baseball in the San Diego system from 1969-71.

Rohn, 49, spent the last 12 seasons as a minor league manager, the past eight in the Mariners organization, including the past five seasons as the AAA Tacoma manager.

In his role as Administrative Coach, Rohn will participate in pre-game work but will not be in uniform for the games. Instead he will be charting the games in the video room. His responsibilities will include building a self-scouting base, and coordinating advance reports and other scouting information on Mariners opponents.

"I'm very pleased and certainly excited to be a part of the big league staff," Rohn said. "It's a good opportunity and I'm looking forward to getting to work with the players on the Major League roster."

Rohn spent the last 12 seasons as a minor league manager, the past eight in the Mariners organization, including the past five seasons as the AAA Tacoma manager. He was named PCL Manager of the Year in both 2004 and 2005.
